" .which is shown in dotted lines of .pitless tum-tables,

tionsextending completely across the turn` `Be it known'that I,- Ronnnr CRAIG, aciti- United States, residing Vat Los Angeles in the county of State of California,v have invented a new and useful Pitless'Tum-Table, of

following is a speciiicatlon.

' My invention relates to automobile turn-l and more particularly to turn-tables tables, i 'which are adapted'to be installed entirely above a floor, without the `necessityr` for the forms of automobile turn-tables. v

Thel principal object of my invention is to provide a pitless turn-table which will be extremely cheap to construct and install, in which necessary, and which requires a minimum amount ofener' to operate.

Referring .to t e drawings, which are for illustrative purposes' only:

Figure 1 l1s a plan view., of a turn table embodying myV invention. f y, .i

Fig. '2 1s a section on a plane represented by the line 21e-2.01:' Fig. 1, this plane being viewed in the direction of the arrows. My invention consists of a track llwhich i. j 1s coneentrically located around a central post 12. Pivoted on the central post 12 is a caring 13 which is formed on a. center arm *14, thls center arm 14 being symmetrical around a line w-a andbeing secured by means of bolts 15 to pan supports 16.

Secu red to eachofythe pan supports. 16, which are symmetrical around'a me b-b, is a wheel pan 17, these pans 17 consisting central portion 18 with beveled ends 19\` which extend down to a point very close to 4the floor 20 upon which the turnftable track is mounted. Secured on the pan ysupports 16, on either -is a pair of wheels 21 bein so located that they travel on 'the trac 1.1.` The wheel pans17 are comparatively short, being properly spaced to receivethe wheels 24 of an automobile 25 in Fig. 2.

This form ofconstruction has required very stii `girder members,

and 'has been' relatively expensive to con-y hard to operate on account of excess weight.

In m form of construction, the short pans on y support the wheels in and near their nal position, the front wheels of the automobile ,rollingover the" first pans onto the floor and bel until the four whee s are ready to pass onto be supported thereby.
